UFC champion Conor McGregor's so pumped about his Floyd Mayweather Jr. fight not even Father's Day can distract him. The sports star has trolled social media, and presumably The Money Team, with some new boxing pics.

The Notorious One went to Instagram Sunday (June 18) with shots of himself in full-fledged training mode.

According to reports, Mayweather is expected to land around $300 million for the August 26 fight.

Floyd Mayweather stepped out in Hollywood Wednesday night ... as the RICHEST ATHLETE TO EVER WALK THE EARTH! Hours after the big McGregor vs. Mayweather announcement, Floyd hit up the "All Eyez On Me" movie premiere in Westwood lookin' like a million bucks (times 300). Floyd has said he expects to make between $200 and $300 million for the McGregor fight - though he hasn't confirmed the terms of the deal yet. (TMZ)
